Pedicularis labradorica
Pedicularis bracteosa
The flowers of Pedicularis labradorica are usually yellow or dark yellow, and the galea is tinged distally with red or purple; sometimes, the yellow color of the tube abruptly transitions into red or purple. Hultén based var. sulphurea on the solid yellow color variant from the Yukon.
